Laundry care compositions containing dyes

ABSTRACT

This application relates to laundry care compositions comprising thiophene azo carboxylate fabric shading dyes and methods of treating a textile comprising such laundry care compositions.

FIELD OF INVENTION

This invention relates to laundry care compositions comprising fabricshading dyes and methods of treatment of fabrics using suchcompositions.

BACKGROUND OF THE INVENTION

As textile substrates age, their color tends to fade or yellow due toexposure to light, air, soil, and natural degradation of the fibers thatcomprise the substrates. To counteract this unwanted effect, laundrydetergent manufacturers incorporate shading dyes into their products.The purpose of shading dyes is typically to counteract the fading andyellowing of the textile substrates by providing a blue-violet hue tothe laundered fabrics, reducing the visual impact of the yellowing.There are many disclosures of shading dyes in detergents. Generallyshading dyes are effective for shading a specific textile type, eithercotton or synthetic fabrics, specifically polyester. Mixtures of dyes ordyes and pigments are generally needed to effect shading across a rangeof textiles, as is described in WO2006/32327 and WO2008/090091.

There is therefore still a need to find dyes that will providedeposition across different types of fibres, such as cotton andsynthetic fibres such as nylon and/or polyester and it is desirable tofind dyes that deposit substantially evenly across different textiletypes and even mixed fibre types, such as polycotton. The presentinvention has been found to alleviate this problem. Furthermore thepresent invention provides compositions that are advantageous inproviding a hueing effect, for example, a whitening effect to fabrics,while not building up over time and causing undesirable discoloration tothe treated fabrics.

Sudssuppression can be of particular importance in the so-called “highconcentration cleaning process” as described in U.S. Pat. Nos. 4,489,455and 4,489,574, and in front-loading-style washing machines. A widevariety of materials may be used as suds suppressors, and sudssuppressors are well known to those skilled in the art. See, forexample, Kirk Othmer Encyclopedia of Chemical Technology, Third Edition,Volume 7, pages 430-447 (John Wiley & Sons, Inc., 1979). Examples ofsuds supressors include monocarboxylic fatty acid and soluble saltstherein, high molecular weight hydrocarbons such as paraffin, fatty acidesters (e.g., fatty acid triglycerides), fatty acid esters of monovalentalcohols, aliphatic C18-C40 ketones (e.g., stearone), N-alkylated aminotriazines, waxy hydrocarbons preferably having a melting point belowabout 100° C., silicone suds suppressors, and secondary alcohols. Sudssupressors are described in U.S. Pat. Nos. 2,954,347; 4,265,779;4,265,779; 3,455,839; 3,933,672; 4,652,392; 4,978,471; 4,983,316;5,288,431; 4,639,489; 4,749,740; and 4,798,679; 4,075,118; EuropeanPatent Application No. 89307851.9; EP 150,872; and DOS 2,124,526.

For any detergent compositions to be used in automatic laundry washingmachines, suds should not form to the extent that they overflow thewashing machine. Suds suppressors, when utilized, are preferably presentin a “suds suppressing amount. By “suds suppressing amount” is meantthat the formulator of the composition can select an amount of this sudscontrolling agent that will sufficiently control the suds to result in alow-sudsing laundry detergent for use in automatic laundry washingmachines. The compositions herein will generally comprise from 0% to 10%of suds suppressor. When utilized as suds suppressors, monocarboxylicfatty acids, and salts therein, will be present typically in amounts upto 5%, by weight, of the detergent composition. Preferably, from 0.5% to3% of fatty monocarboxylate suds suppressor is utilized. Silicone sudssuppressors are typically utilized in amounts up to 2.0%, by weight, ofthe detergent composition, although higher amounts may be used.Monostearyl phosphate suds suppressors are generally utilized in amountsranging from 0.1% to 2%, by weight, of the composition. Hydrocarbon sudssuppressors are typically utilized in amounts ranging from 0.01% to5.0%, although higher levels can be used. The alcohol suds suppressorsare typically used at 0.2%-3% by weight of the finished compositions.

The compositions of the invention may be in any useful form, asdescribed above. They may be made by any process chosen by theformulator, non-limiting examples of which are described in the examplesand in U.S. Pat. No. 4,990,280; U.S. 20030087791A1; U.S. 20030087790A1;U.S. 20050003983A1; U.S. 20040048764A1; U.S. Pat. No. 4,762,636; U.S.Pat. No. 6,291,412; U.S. 20050227891A1; EP 1070115A2; U.S. Pat. No.5,879,584; U.S. Pat. No. 5,691,297; U.S. Pat. No. 5,574,005; U.S. Pat.No. 5,569,645; U.S. Pat. No. 5,565,422; U.S. Pat. No. 5,516,448; U.S.Pat. No. 5,489,392; U.S. Pat. No. 5,486.

When in the form of a liquid, the laundry care compositions of theinvention may be aqueous (typically above 2 wt % or even above 5 or 10wt % total water, up to 90 or up to 80 wt % or 70 wt % total water) ornon-aqueous (typically below 2 wt % total water content). Typically thecompositions of the invention will be in the form of an aqueous solutionor uniform dispersion or suspension of surfactant, shading dye, andcertain optional other ingredients, some of which may normally be insolid form, that have been combined with the normally liquid componentsof the composition, such as the liquid alcohol ethoxylate nonionic, theaqueous liquid carrier, and any other normally liquid optionalingredients. Such a solution, dispersion or suspension will beacceptably phase stable. When in the form of a liquid, the laundry carecompositions of the invention preferably have viscosity from 1 to 1500centipoises (1-1500 mPa*s), more preferably from 100 to 1000 centipoises(100-1000 mPa*s), and most preferably from 200 to 500 centipoises(200-500 mPa*s) at 20s-1 and 21° C. Viscosity can be determined byconventional methods. Viscosity may be measured using an AR 550rheometer from TA instruments using a plate steel spindle at 40 mmdiameter and a gap size of 500 μm. The high shear viscosity at 20s-1 andlow shear viscosity at 0.05-1 can be obtained from a logarithmic shearrate sweep from 0.1-1 to 25-1 in 3 minutes time at 21 C. The preferredrheology described therein may be achieved using internal existingstructuring with detergent ingredients or by employing an externalrheology modifier. More preferably the laundry care compositions, suchas detergent liquid compositions have a high shear rate viscosity offrom about 100 centipoise to 1500 centipoise, more preferably from 100to 1000 cps. Unit Dose laundry care compositions, such as detergentliquid compositions have high shear rate viscosity of from 400 to 1000cps. Laundry care compositions such as laundry softening compositionstypically have high shear rate viscosity of from 10 to 1000, morepreferably from 10 to 800 cps, most preferably from 10 to 500 cps. Handdishwashing compositions have high shear rate viscosity of from 300 to4000 cps, more preferably 300 to 1000 cps.

The liquid compositions, preferably liquid detergent compositions hereincan be prepared by combining the components thereof in any convenientorder and by mixing, e.g., agitating, the resulting componentcombination to form a phase stable liquid detergent composition. In aprocess for preparing such compositions, a liquid matrix is formedcontaining at least a major proportion, or even substantially all, ofthe liquid components, e.g., nonionic surfactant, the non-surface activeliquid carriers and other optional liquid components, with the liquidcomponents being thoroughly admixed by imparting shear agitation to thisliquid combination. For example, rapid stirring with a mechanicalstirrer may usefully be employed. While shear agitation is maintained,substantially all of any anionic surfactants and the solid formingredients can be added. Agitation of the mixture is continued, and ifnecessary, can be increased at this point to form a solution or auniform dispersion of insoluble solid phase particulates within theliquid phase. After some or all of the solid-form materials have beenadded to this agitated mixture, particles of any enzyme material to beincluded, e.g., enzyme prills, are incorporated. As a variation of thecomposition preparation procedure hereinbefore described, one or more ofthe solid components may be added to the agitated mixture as a solutionor slurry of particles premixed with a minor portion of one or more ofthe liquid components. After addition of all of the compositioncomponents, agitation of the mixture is continued for a period of timesufficient to form compositions having the requisite viscosity and phasestability characteristics. Frequently this will involve agitation for aperiod of from about 30 to 60 minutes.

In one aspect of forming the liquid compositions, the dye is firstcombined with one or more liquid components to form a dye premix, andthis dye premix is added to a composition formulation containing asubstantial portion, for example more than 50% by weight, morespecifically, more than 70% by weight, and yet more specifically, morethan 90% by weight, of the balance of components of the laundrydetergent composition. For example, in the methodology described above,both the dye premix and the enzyme component are added at a final stageof component additions. In another aspect, the dye is encapsulated priorto addition to the detergent composition, the encapsulated dye issuspended in a structured liquid, and the suspension is added to acomposition formulation containing a substantial portion of the balanceof components of the laundry detergent composition.

Pouches.

In a preferred embodiment of the invention, the composition is providedin the form of a unitized dose, either tablet form or preferably in theform of a liquid/solid (optionally granules)/gel/paste held within awater-soluble film in what is known as a pouch or pod. The compositioncan be encapsulated in a single or multi-compartment pouch.Multi-compartment pouches are described in more detail in EP-A-2133410.When the composition is present in a multi-compartment pouch, thecomposition of the invention may be in one or two or more compartments,thus the dye may be present in one or more compartments, optionally allcompartments. Non-shading dyes or pigments or other aesthetics may alsobe used in one or more compartments. In one embodiment the compositionis present in a single compartment of a multi-compartment pouch.

Suitable film for forming the pouches is soluble or dispersible inwater, and preferably has a water-solubility/dispersibility of at least50%, preferably at least 75% or even at least 95%, as measured by themethod set out here after using a glass-filter with a maximum pore sizeof 20 microns:

50 grams±0.1 gram of pouch material is added in a pre-weighed 400 mlbeaker and 245 ml±1 ml of distilled water is added. This is stirredvigorously on a magnetic stirrer set at 600 rpm, for 30 minutes. Then,the mixture is filtered through a folded qualitative sintered-glassfilter with a pore size as defined above (max. 20 micron). The water isdried off from the collected filtrate by any conventional method, andthe weight of the remaining material is determined (which is thedissolved or dispersed fraction). Then, the percentage solubility ordispersability can be calculated. Preferred film materials are polymericmaterials. The film material can be obtained, for example, by casting,blow-moulding, extrusion or blown extrusion of the polymeric material,as known in the art. Preferred polymers, copolymers or derivativesthereof suitable for use as pouch material are selected from polyvinylalcohols, polyvinyl pyrrolidone, polyalkylene oxides, acrylamide,acrylic acid, cellulose, cellulose ethers, cellulose esters, celluloseamides, polyvinyl acetates, polycarboxylic acids and salts,polyaminoacids or peptides, polyamides, polyacrylamide, copolymers ofmaleic/acrylic acids, polysaccharides including starch and gelatine,natural gums such as xanthum and carragum. More preferred polymers areselected from polyacrylates and water-soluble acrylate copolymers,methylcellulose, carboxymethylcellulose sodium, dextrin, ethylcellulose,hydroxyethyl cellulose, hydroxypropyl methylcellulose, maltodextrin,polymethacrylates, and most preferably selected from polyvinyl alcohols,polyvinyl alcohol copolymers and hydroxypropyl methyl cellulose (HPMC),and combinations thereof. Preferably, the level of polymer in the pouchmaterial, for example a PVA polymer, is at least 60%. The polymer canhave any weight average molecular weight, preferably from about 1000 to1,000,000, more preferably from about 10,000 to 300,000 yet morepreferably from about 20,000 to 150,000. Mixtures of polymers can alsobe used as the pouch material. This can be beneficial to control themechanical and/or dissolution properties of the compartments or pouch,depending on the application thereof and the required needs. Suitablemixtures include for example mixtures wherein one polymer has a higherwater-solubility than another polymer, and/or one polymer has a highermechanical strength than another polymer. Also suitable are mixtures ofpolymers having different weight average molecular weights, for examplea mixture of PVA or a copolymer thereof of a weight average molecularweight of about 10,000-40,000, preferably around 20,000, and of PVA orcopolymer thereof, with a weight average molecular weight of about100,000 to 300,000, preferably around 150,000. Also suitable herein arepolymer blend compositions, for example comprising hydrolyticallydegradable and water-soluble polymer blends such as polylactide andpolyvinyl alcohol, obtained by mixing polylactide and polyvinyl alcohol,typically comprising about 1-35% by weight polylactide and about 65% to99% by weight polyvinyl alcohol. Preferred for use herein are polymerswhich are from about 60% to about 98% hydrolysed, preferably about 80%to about 90% hydrolysed, to improve the dissolution characteristics ofthe material.

Naturally, different film material and/or films of different thicknessmay be employed in making the compartments of the present invention. Abenefit in selecting different films is that the resulting compartmentsmay exhibit different solubility or release characteristics.

Most preferred film materials are PVA films known under the MonoSoltrade reference M8630, M8900, H8779 (as described in the Applicantsco-pending applications ref 44528 and 11599) and those described in U.S.Pat. No. 6,166,117 and U.S. Pat. No. 6,787,512 and PVA films ofcorresponding solubility and deformability characteristics.

The film material herein can also comprise one or more additiveingredients. For example, it can be beneficial to add plasticisers, forexample glycerol, ethylene glycol, diethyleneglycol, propylene glycol,sorbitol and mixtures thereof. Other additives include functionaldetergent additives to be delivered to the wash water, for exampleorganic polymeric dispersants, etc.

Process for Making the Water-Soluble Pouch

The compositions of the invention in pouch form may be made using anysuitable equipment and method. However the multi-compartment pouches arepreferably made using the horizontal form filling process. The film ispreferably wetting, more preferably heated to increase the malleabilitythereof. Even more preferably, the method also involves the use of avacuum to draw the film into a suitable mould. The vacuum drawing thefilm into the mould can be applied for 0.2 to 5 seconds, preferably 0.3to 3 or even more preferably 0.5 to 1.5 seconds, once the film is on thehorizontal portion of the surface. This vacuum may preferably be suchthat it provides an under-pressure of between −100 mbar to −1000 mbar,or even from −200 mbar to −600 mbar.

The moulds, in which the pouches are made, can have any shape, length,width and depth, depending on the required dimensions of the pouches.The moulds can also vary in size and shape from one to another, ifdesirable. For example, it may be preferred that the volume of the finalpouches is between 5 and 300 ml, or even 10 and 150 ml or even 20 and100 ml and that the mould sizes are adjusted accordingly.

Heat can be applied to the film, in the process commonly known asthermoforming, by any means. For example the film may be heated directlyby passing it under a heating element or through hot air, prior tofeeding it onto the surface or once on the surface. Alternatively it maybe heated indirectly, for example by heating the surface or applying ahot item onto the film. Most preferably the film is heated using aninfra red light. The film is preferably heated to a temperature of 50 to120° C., or even 60 to 90° C. Alternatively, the film can be wetted byany mean, for example directly by spraying a wetting agent (includingwater, solutions of the film material or plasticizers for the filmmaterial) onto the film, prior to feeding it onto the surface or once onthe surface, or indirectly by wetting the surface or by applying a wetitem onto the film.

In the case of pouches comprising powders it is advantageous to pinprick the film for a number of reasons: (a) to reduce the possibility offilm defects during the pouch formation, for example film defects givingrise to rupture of the film can be generated if the stretching of thefilm is too fast; (b) to permit the release of any gases derived fromthe product enclosed in the pouch, as for example oxygen formation inthe case of powders containing bleach; and/or (c) to allow thecontinuous release of perfume. Moreover, when heat and/or wetting isused, pin pricking can be used before, during or after the use of thevacuum, preferably during or before application of the vacuum. Preferredis thus that each mould comprises one or more holes which are connectedto a system which can provide a vacuum through these holes, onto thefilm above the holes, as described herein in more detail.

Once a film has been heated/wetted, it is drawn into an appropriatemould, preferably using a vacuum. The filling of the moulded film can bedone by any known method for filling (moving) items. The most preferredmethod will depend on the product form and speed of filling required.Preferably the moulded film is filled by in-line filling techniques. Thefilled, open pouches are then closed, using a second film, by anysuitable method. Preferably, this is also done while in horizontalposition and in continuous, constant motion. Preferably the closing isdone by continuously feeding a second material or film, preferablywater-soluble film, over and onto the web of open pouches and thenpreferably sealing the first film and second film together, typically inthe area between the moulds and thus between the pouches.

Preferred methods of sealing include heat sealing, solvent welding, andsolvent or wet sealing. It is preferred that only the area which is toform the seal, is treated with heat or solvent. The heat or solvent canbe applied by any method, preferably on the closing material, preferablyonly on the areas which are to form the seal. If solvent or wet sealingor welding is used, it may be preferred that heat is also applied.Preferred wet or solvent sealing/welding methods include applyingselectively solvent onto the area between the moulds, or on the closingmaterial, by for example, spraying or printing this onto these areas,and then applying pressure onto these areas, to form the seal. Sealingrolls and belts as described above (optionally also providing heat) canbe used, for example.

The formed pouches can then be cut by a cutting device. Cutting can bedone using any known method. It may be preferred that the cutting isalso done in continuous manner, and preferably with constant speed andpreferably while in horizontal position. The cutting device can, forexample, be a sharp item or a hot item, whereby in the latter case, thehot item ‘burns’ through the film/sealing area.

The different compartments of a multi-compartment pouch may be madetogether in a side-by-side style and consecutive pouches are not cut.Alternatively, the compartments can be made separately. According tothis process and preferred arrangement, the pouches are made accordingto the process comprising the steps of:

-   -   a) forming an first compartment (as described above);    -   b) forming a recess within some or all of the closed compartment        formed in step (a), to generate a second moulded compartment        superposed above the first compartment;    -   c) filling and closing the second compartments by means of a        third film;    -   d) sealing said first, second and third films; and    -   e) cutting the films to produce a multi-compartment pouch.

Said recess formed in step b is preferably achieved by applying a vacuumto the compartment prepared in step a).

Alternatively the second, and optionally third, compartment(s) can bemade in a separate step and then combined with the first compartment asdescribed in our co-pending application EP 08101442.5 which isincorporated herein by reference. A particularly preferred processcomprises the steps of:

-   -   a) forming a first compartment, optionally using heat and/or        vacuum, using a first film on a first forming machine;    -   b) filling said first compartment with a first composition;    -   c) on a second forming machine, deforming a second film,        optionally using heat and vacuum, to make a second and        optionally third moulded compartment;    -   d) filling the second and optionally third compartments;    -   e) sealing the second and optionally third compartment using a        third film;    -   f) placing the sealed second and optionally third compartments        onto the first compartment;    -   g) sealing the first, second and optionally third compartments;        and    -   h) cutting the films to produce a multi-compartment pouch

The first and second forming machines are selected based on theirsuitability to perform the above process. The first forming machine ispreferably a horizontal forming machine. The second forming machine ispreferably a rotary drum forming machine, preferably located above thefirst forming machine.

It will be understood moreover that by the use of appropriate feedstations, it is possible to manufacture multi-compartment pouchesincorporating a number of different or distinctive compositions and/ordifferent or distinctive liquid, gel or paste compositions.

Solid Form.

As noted previously, the laundry care compositions may be in a solidform. Suitable solid forms include tablets and particulate forms, forexample, granular particles, flakes or sheets. Various techniques forforming detergent compositions in such solid forms are well known in theart and may be used herein. In one aspect, for example when thecomposition is in the form of a granular particle, the dye is providedin particulate form, optionally including additional but not allcomponents of the laundry detergent composition. The dye particulate iscombined with one or more additional particulates containing a balanceof components of the laundry detergent composition. Further, the dye,optionally including additional but not all components of the laundrydetergent composition, may be provided in an encapsulated form, and theshading dye encapsulate is combined with particulates containing asubstantial balance of components of the laundry detergent composition.Suitable pre-mix particles for incorporation of dyes/benefit agents intolaundry care compositions of the invention are described for example inWO2010/084039, WO2007/039042, WO2010/022775, WO2009/132870,WO2009/087033, WO2007/006357, WO2007/039042, WO2007/096052,WO2011/020991, WO2006/053598, WO2003/018740 and WO2003/018738.

Method of Use. The compositions of this invention, prepared ashereinbefore described, can be used to form aqueous washing/treatmentsolutions for use in the laundering/treatment of fabrics. Generally, aneffective amount of such compositions is added to water, for example ina conventional fabric automatic washing machine, to form such aqueouslaundering solutions. The aqueous washing solution so formed is thencontacted, typically under agitation, with the fabrics to belaundered/treated therewith. An effective amount of the liquid detergentcompositions herein added to water to form aqueous laundering solutionscan comprise amounts sufficient to form from about 500 to 7,000 ppm ofcomposition in aqueous washing solution, or from about 1,000 to 3,000ppm of the detergent compositions herein will be provided in aqueouswashing solution.

Typically, the wash liquor is formed by contacting the laundry carecomposition with wash water in such an amount so that the concentrationof the laundry care composition in the wash liquor is from above 0 g/lto 5 g/l, or from 1 g/l, and to 4.5 g/l, or to 4.0 g/l, or to 3.5 g/l,or to 3.0 g/l, or to 2.5 g/l, or even to 2.0 g/l, or even to 1.5 g/l.The method of laundering fabric or textile may be carried out in atop-loading or front-loading automatic washing machine, or can be usedin a hand-wash laundry application. In these applications, the washliquor formed and concentration of laundry detergent composition in thewash liquor is that of the main wash cycle. Any input of water duringany optional rinsing step(s) is not included when determining the volumeof the wash liquor.

The wash liquor may comprise 40 litres or less of water, or 30 litres orless, or 20 litres or less, or 10 litres or less, or 8 litres or less,or even 6 litres or less of water. The wash liquor may comprise fromabove 0 to 15 litres, or from 2 litres, and to 12 litres, or even to 8litres of water. Typically from 0.01 kg to 2 kg of fabric per litre ofwash liquor is dosed into said wash liquor. Typically from 0.01 kg, orfrom 0.05 kg, or from 0.07 kg, or from 0.10 kg, or from 0.15 kg, or from0.20 kg, or from 0.25 kg fabric per litre of wash liquor is dosed intosaid wash liquor. Optionally, 50 g or less, or 45 g or less, or 40 g orless, or 35 g or less, or 30 g or less, or 25 g or less, or 20 g orless, or even 15 g or less, or even 10 g or less of the composition iscontacted to water to form the wash liquor. Such compositions aretypically employed at concentrations of from about 500 ppm to about15,000 ppm in solution. When the wash solvent is water, the watertemperature typically ranges from about 5° C. to about 90° C. and, whenthe situs comprises a fabric, the water to fabric ratio is typicallyfrom about 1:1 to about 30:1. Typically the wash liquor comprising thelaundry care composition of the invention has a pH of from 3 to 11.5.

In one aspect, such method comprises the steps of optionally washingand/or rinsing said surface or fabric, contacting said surface or fabricwith any composition disclosed in this specification then optionallywashing and/or rinsing said surface or fabric is disclosed, with anoptional drying step.

Drying of such surfaces or fabrics may be accomplished by any one of thecommon means employed either in domestic or industrial settings. Thefabric may comprise any fabric capable of being laundered in normalconsumer or institutional use conditions, and the invention isparticularly suitable for synthetic textiles such as polyester and nylonand especially for treatment of mixed fabrics and/or fibres comprisingsynthetic and cellulosic fabrics and/or fibres. As examples of syntheticfabrics are polyester, nylon, these may be present in mixtures withcellulosic fibres, for example, polycotton fabrics. The solutiontypically has a pH of from 7 to 11, more usually 8 to 10.5. Thecompositions are typically employed at concentrations from 500 ppm to5,000 ppm in solution. The water temperatures typically range from about5° C. to about 90° C. The water to fabric ratio is typically from about1:1 to about 30:1.

Test Methods

I. Method for Determining Hueing Deposition (HD) for Dye from a WashSolution

Unbrightened mulitfiber fabric swatches are stripped prior to use bywashing at 49° C. two times with heavy duty liquid laundry detergent nilbrightener (1.55 g/L in aqueous solution). A concentrated stock solutionof each dye to be tested is prepared in a solvent selected from dimethylsulfoxide, ethanol or 50:50 ethanol:water. Dye stocks are added tobeakers containing 400 mL detergent in water (heavy duty liquid laundrydetergent nil brightener, 1.55 g per liter) to produce a wash solutionwith an absorbance of 0.4 AU (±0.01AU; 1.0 cm cuvette) at the λ_(max) ofthe dye.

A 125 mL aliquot of each wash solution is placed into three 250 mLErlenmeyer flasks, each containing four swatches. The flasks are placedon a Model 75 wrist action shaker (Burrell Scientific, Inc., Pittsburgh,Pa.) and agitated at the maximum setting for 12 minutes, after which thewash solution is removed by aspiration, 125 mL of rinse water (0 gpg) isadded before agitating 4 more minutes. The rinse is removed byaspiration and the fabric swatches are spun dry (Mini Countertop SpinDryer, The Laundry Alternative Inc., Nashua, N.H.) for 5 minutes, thenplaced in the dark to dry.

L*, a*, and b* values for cotton, nylon and polyester are measured onthe dry swatches using a LabScan XE reflectance spectrophotometer(HunterLabs, Reston, Va.; D65 illumination, 10° observer, UV lightexcluded). The L*, a*, and b* values of the 12 swatches generated foreach dye are averaged and the hueing deposition (HD) of each dye iscalculated for each fabric type using the following equation:

HD=DE*=((L* _(c) −L* _(s))²+(a* _(c) −a* _(s))²+(b* _(c) −b*_(s))²)^(1/2)

wherein the subscripts c and s respectively refer to the control, i.e.,the fabric washed in detergent with no dye, and the sample, i.e., thefabric washed in detergent containing dye.

II. Method for Determining Deposition Index (DI)

The parameters described in II. (a.)-(d.) below are calculated only whenat least one of the individual deposition (HD) values for cotton,polyamide and polyester is ≧2.0.

a.) the Average Deposition (AHD) is calculated using the following:

AHD=(Cotton HD+Nylon HD+Polyester HD)/3

b.) The Hueing Deposition Variation (DV) is calculated using thefollowing:

DV=Largest HD−Smallest HD

c.) From the AHD and HDV we derive the Hueing Deposition Homogeneity(HDH) using the following formula:

HDH=AHD/(AHD+DV) i.e. a value of 1.0 represents a perfect dye, one thatdeposits equally well on all three fabrics.

d.) The Hueing Deposition Index (DI) is calculated as follows:

DI=AHD×HDH

EXAMPLES Performance Example 1

The performance of Dye A (comparative) and Dye B (Example 5 fromTable 1) are tested and Hueing Deposition, Hueing Deposition Variationand Deposition Index are assessed according to the equations disclosedin the methods. The results are given in Table 2.

Both dyes show deposition across each fabric type, with similar averagedeposition values, but Dye B not only deposits more than Dye A, Dye Bhas a more even deposition profile than Dye A, as seen in the Hueing DyeHomogeneity index values, where a value of 1.0 represents a perfect dye,one that deposits equally well on all three fabrics. This results in abetter hueing dye index, which is a measure that relates to the abilityof the dye both to deposit well and to deposit evenly across all threefabrics.

One further problem which is alleviated by the compositions and methodsof the present invention is that typically although the hue provided bya fabric shading dye would be identical independent of the fabric type,in practice this is not normally the case, and the hue typically shiftsconsiderably depending on the fabric on which it resides. Thecompositions and methods of the present invention alleviate thisproblem: the hue shift provided is lower than that produced with priorart dyes between cellulosic and synthetic fabrics and/or fibres andbetween different synthetic fabrics and/or fibres.

Thus the compositions and methods of the invention provide gooddeposition across a range of fabrics, both extent and evenness, theconsistency of the hue it imparts to those fabrics, and its ability tobe removed in subsequent washes is also good, avoiding overhueing evenon synthetic fabrics such as nylon.
